that a frame must be received at the speciﬁed port for the ﬁltering action to apply.

To do so, click on the Receive port in the panel. With each click, the Receive port

will cycle to the next port (e.g., from * (promiscuous), to 1, to 2, to 3, to 4, to 5, to 6

(etc., up to the total number of installed interfaces), and back to *.

When you reconﬁgure the Filtering Database and click , the screen will clear

temporarily and a message will appear to indicate that the information is being updated.

When the changes have been successfully set and the Filtering Database has updated, the

screen information will be refreshed.

NOTE

Note that the Filtering Database Ageing Time is the same as the Ageing Time displayed

(and conﬁgured) via the Port X Source Addresses window; setting the Ageing Time in the

Filtering Database window also changes the time in the Source Addresses window, and

vice versa.

TIP

If you wish to change the port ﬁltering action for a Learned address entry, you must ﬁrst

change its entry type to Permanent, Static, or Dynamic.
